Meta CEO Mark Zuckerberg returned to X (formerly Twitter) after nearly three years to announce the public release of Meta’s new AI model, Muse Spark 1.1. His posts drew a response from X owner Elon Musk, who said the platform offers companies a way to reach millions of users directly without relying on traditional press releases. Announcing the launch, Zuckerberg wrote, “Today we’re releasing Muse Spark 1.1 — a strong agentic and coding model at a very low price. It’s available through our new Meta Model API and in Meta AI.”

Replying to the announcement, Musk wrote, “X is a great platform for product announcements, especially if done by the CEO directly. Way more interesting to the public than generic press releases. This post by Mark Zuckerberg already received over 12 million views for free!”
